Abstract: An inductive power transfer apparatus may be used for producing or receiving a magnetic field for inductive power transfer. The apparatus has a central coil and two end coils, one of the end coils being provided at each end of the central coil. Some turns of each of the end coils are on one side of the central coil and the remaining turns are on the other side. The end coils act to weaken or cancel flux on one side of the central coil and guide magnetic flux through the central coil to provide an arch shaped flux pattern beyond the apparatus on the other side of the central coil.

Abstract: An inductive power transfer (IPT) control method is disclosed for controlling the output of an IPT pick-up. The invention involves selectively shunting first and second diodes of a diode bridge to selectively rectify an AC current input for supply to a load, or recirculate the AC current to a resonant circuit coupled to the input of the controller. By controlling the proportion of each positive-negative cycle of the AC input which is rectified/recirculated, the output is regulated. Also disclosed is an IPT controller adapted to perform the method, an IPT pick-up incorporating the IPT controller, and an IPT system incorporating at least one such IPT pick-up. (FIG.

Abstract: An inductive power transfer (IPT) pick-up circuit has a full-wave rectifier (D1-D4) coupled to a resonant circuit (L1 C1) and adapted to rectify an AC current received from the resonant circuit. A pair of inductors (L2 L3) are provided, being arranged to couple the rectifier to an output (VLoad) of the pick-up circuit and alternately store and release energy to the output.

Abstract: An interactive greeting card with a multi-panel insert which can be unfurled over a portion of the greeting card. In one embodiment, there is a photo or drawing of a character or animal printed on the front cover. A tab is located to the left of and behind the photo or drawing. When a user grasps and moves the tab, a multi-panel paper construct unfurls around the photo or drawing and appears as a wig atop the head of the character or animal depicted in the photo or drawing. Audio replay may also triggered by moving the tab from its original position. In another embodiment, the panels of the multi-panel paper construct are each shaped like a different item or object which is complementary to the theme of the greeting card. Unfolding the multi-panel construct along an outside edge of the greeting card may initiate audio playback and may also activate a motor module which causes movement to at least one mobile object contained on the greeting card.

Abstract: The present invention is directed to a greeting card which combines a pop-up element with audio and motor movement. The greeting card contains two different sized pop-up panels which are spaced apart and parallel to one another. Two die cut shapes serve as mobile objects which spin or rotate upon opening the greeting card. The size and placement of the pop-up panels and the mobile objects create a three-dimensional scene. A slide trigger initiates audio playback and motor movement of the mobile objects upon opening the greeting card.

Abstract: The greeting card of the present invention is a traditional greeting card enhanced by audio and movement. The greeting card contains a pull trigger mechanism so that the user must interact with the greeting card to trigger the audio and motor movement. The pull trigger mechanism may be made of a variety of different materials and are intended to resemble the tail of various animals. Once the pull mechanism or tail has been pulled, the motor is activated causing movement of a portion of the greeting card proximate to the pull mechanism or tail which resembles the behind of an animal. The moveable portion of the greeting card moves, by for example back and forth, while audio plays in the background.
